The input shaft is a one piece shaft so no possibility of the pin shearing.  Ratio is 3.17 ; 1 and the planetry housing is machined from solid to ensure no failures.  All based on the Ford gears.  I should note a warning to any with a ford planetry that having dismantled 8 of these (48 assemblies)  I have found 2 sun gears with one needle roller missing from the bearing set.

>     Price for the first 5 is $5500 USD which is slightly discounted due to damage in transit of the alloy cushion drives. Mounting plate is an extra and sold by Randy kempf. Freight is $300 and max insurance I can get for another $200 is $5000 AUD which is $3800 USD.
